Wood as a Raw Material is essentially the same course that over
3,000 forestry and wood products students have completed while
studying at the University of Minnesota Twin Cities Campus. This
course is now available as a distance education offering using
a University of Minnesota-produced CD-ROM The
Nature of Wood and Wood Products in combination with unlimited
access to U of M instructors throughout the course of study.
Topics include:
- The nature of wood.
- How properties of various kinds of wood differ and why.
- Techniques for modifying wood properties so as to improve performance.
- Fundamental characteristics of the principal wood products
and essential features that define their proper application and
use.
- Limitations to wood use.
- How wood products are measured and units used in commercial
trade.

Syllabus
Organization of the course:
This course is administered via a series of independent study
sessions based on the CD-ROM The Nature
of Wood and Wood Products and on the textbook Forest
Products and Wood Science - an Introduction.
The anatomical structure of wood will be the subject of the first
one-third of the course, followed in the next one-third by a study
of wood's physical properties. An examination of raw material measurement
and conversion to useful products will conclude the course.
Individuals for whom the course is intended:
- Students in the Forest Resources curriculum take this course
to gain a basic understanding of what the forest products industries
produce, the raw material used by these industries, and the nature
and properties of wood which affect how and what kind of wood
materials can be utilized.
- Bio-based Products students take this course as an introduction
to the field to provide them an information base for further
courses they will take in forest products. This is designed as
a sophomore level course. No previous knowledge of forestry or
forest products is assumed. Transfer students should take this
course as soon as possible after transfer, most commonly in fall
quarter of their junior year.
- Non-forestry or forest products students who are interested
in learning more about wood as a construction and general use
material
Course Objectives:
There are two general objectives of the course:
- To allow students to learn of the physical nature of wood
and how this physical nature affects both the type of products
which can be made from wood and the properties of these products.
Unless the student has a firm understanding of what wood is and
how it varies between and within species, problems which arise
in its utilization cannot be fully appreciated. Foresters are
very often involved directly in these problems of utilization.
- To provide students with an understanding of the industries
which depend upon wood for their raw materials, the type and
quality of wood required by these industries, and the method
of measuring and evaluating various types of wood raw materials.
Grading in the course:
The students' final grade for the course will be determined by
two exams given during the semester which will each comprise 30%
of the grade and by the final examination which will make up the
remaining 40%. All students are required to take the final
examination.
Exams will cover material covered in assigned readings, in CD-ROM
modules, and in problem sets. As part of preparation for examinations
students are strongly encouraged to study review sections found
at the end of each chapter in the course text and at the end of
each module on the CD.
The following is reproduced from an earlier College bulletin and
explains the grading philosophy in this course:
A - Achievement that is outstanding relative to the level necessary
to meet course requirements.
B - Achievement significantly above the level necessary to meet course requirements.
C - Achievement that meets the basic course requirements in every respect.
D - Achievement worthy of credit even though it does not fully meet the basic
course requirements in every respect.
S - Achievement satisfactory to the instructor, for the program in which the
student is registered. This definition is intended to imply that the standards
for S may vary from one program to another.
F - Assigned when the student does not earn an S or a D or higher and is not
assigned an I.
